Question

6. What is the dimensional formula of gravitational constant?
​

Answer 1

or, G = M^-1 L...

i.e,. F = G(m1×m2)/d^2 , where m1 & m2 are the masses of the two bodies, d is the distance between the two bodies and G is the gravitational constant. We know that the units of Force are MLT^-2.

Answer 2

Derivation. Or, G = [M1 L1 T-2] × [L]2 × [M]-2 = [M-1 L3 T-2]. Therefore, the gravitational constant is dimensionally represented as M-1 L3 T-2.
